Carrie Underwood turns the big 3-0 today! To celebrate this milestone in the country music star’s life, we take a look at her metamorphosis over the years from American Idol newbie to country’s reigning queen.

An Idol is born

Fans first met Carrie Underwood on Season 4 of American Idol and quickly fell in love with the unassuming farm girl from Checotah, Oklahoma with killer pipes. On March 4, 2005, Simon Cowell’s early prediction for the competition came true when Carrie took home the season’s top honors.

After her American Idol win, Carrie embarked on a whirlwind tour of concerts and press appearances. Judging by her baggy dress and leather fringe belt, it seems likely she’d yet to hire a stylist during her June 2005 performance on The TODAY Show.

Still her own stylist

One of her first appearances on the late-night talk-show circuit, Carrie arrived at the Ed Sullivan Theater for the Late Show with David Letterman wearing a laid-back ensemble of cargo pants, a hoodie and a Country Western-style studded handbag.

In 2007, Carrie really started to come out of her shell. She showed up at the American Music Awards that year looking super-chic and markedly more svelte in a Georges Chakra white minidress — perhaps the official start of her glamorous evolution.

A new fashion darling

Miss Underwood made major waves at the 50th Annual Grammy Awards in a floor-sweeping, floral-print Zuhair Murad gown, which landed her on many “best dressed” lists. The stylish star picked up the Best Female Country Vocal Performance award.

Carrie, 2.0

When the country cutie returned to the Ed Sullivan Theater in 2009 for the Late Show with David Letterman, she more than redeemed herself for her fashion indiscretion during her prior appearance. This go-round, she nailed casual chic.

The look of love

Carrie’s sophisticated dress at the 52nd Annual Grammy Awards did its part to make the star radiate, but her true glow came from being in love. She walked the event’s red carpet in 2010 with fiancé Mike Fisher, mere months shy of their wedding day.

Carrie was the definition of a country crossover icon while performing on her “Blown Away” tour at Mandalay Bay Resort and Casino in Las Vegas. Her stage style has become epic over the years, replete with sky-high heels and designer duds.

A true show-stopper

During her performance at the 55th Annual Grammy Awards earlier this year, Carrie stole the night. The now-mainstream star’s silver Theia ballgown transformed on stage from simple to stunning by illumination with flickering images and bright colors.
